Colonic irrigator



July 3, 1962 E. J. DAHLSTROM COLONIC IRRIGATOR Filed NOV. 12, 1959 INVENTOR. EDWARD J DAHLSTROM W, WW1

ATTORNEYS Unite grates This invention relates to a colonic irrigator and has for its principal object the production of a sanitary portable irrigator primarily intended for home use and which can be readily and conveniently used by a patient when seated on a toilet.

Other objects and advantages of the invention are to provide means for detachably retaining the device on the toilet seat by the legs of the operator on said seat; to provide a handle to operate a choke wire or Bowden cable that serves to operate one valve and to close another valve; means for directing and controlling the flow of a fluid from a suspended source of fluid supply to an injection tube that transfers the liquid to the colon to flush the same.

A further object of the invention is the production of an irrigator of the character described that is simple in construction, economical to manufacture, positive in operation, strong, durable and highly efiicient and serviceable in use.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and wherein for the purpose of illustration like numerals refer to like parts throughout the same.

FIG. 1 is a side elevational view of the device showing the same in use;

FIG. 2 is a side elevational view of the device on an enlarged scale;

FIG. 3 is a fragmentary view in front elevation of the cross strip of the invention and the handle positioned relative thereto; and,

FIG. 4 is a fragmentary view in perspective illustrating the pivotal arrangement of the frame relative to the colon tube.

Referring to the drawings the numeral 5 designates a liquid holding bag that is adapted to be suspended from a wall or other suitable support 6. A rubber tube 7 leads from the bag and is suitably connected to the open end of a flexible conduit 7' preferably made of metal. The conduit is horizontally disposed adjacent to its open end, then curves downwardly as at 8 and upwardly as at 9 for connection with a vertical plug valve 10 having an operating handle 11 restricted to movement through 90 degrees from an open position to a closed position at the ends of its movement. It will be noted that a rectangular shaped flat cross-strip 12 rests transversely on the top front portion of a toilet seat 13 and the horizontal portion 7 of the conduit is soldered or otherwise secured to said strip. This strip is adapted to be held against the toilet seat by the thighs of the user when the patient is in a seated posture. Downward pressure of the thighs on the strip retains the device in an operative position on the bowl seat.

Secured to the upper end of the valve 10 by a fitting 14 is a discharge nozzle 16 adapted to enter the anal canal, which nozzle is open ended as at 17 and 18 and receives therein fluid from the conduit to flush the colon when the valve 10 is opened and the flap valve 19 is closed.

The mechanism for pivotally mounting the flap valve on the tube 16, comprises a frame as disclosed to advantage in FIG. 4. This frame consists of a rear portion 20 having two side arms 21 and two depending arms 22, the latter being connected at their ends to the flap valve atent Sh t-2,23%

19. A cross shaft 23 is soldered or otherwise suitably secured to the outer periphery of the tube 16 and loosely mounted at its ends in the side arms of the frame. This cross shafts permits the pivotal action of the flap valve to cover and uncover the bottom open end 18 of the tube 16, which action is illustrated to advantage by dotted and full lines in FIG. 2 of the drawing.

Extending upwardly from one of the side arms 21 is an angular extension 24 to which is connected the upper end of a coil spring 25, the opposite end of the spring being connected to the handle 11 of the plug valve 10. This spring provides a yieldable connection between the valve handle 11 and the extension 24, and is shown in full line in FlG. 2 in substantially its normal compressed and extended position so as to function as a resilient, yieldable, push and pull rod. This yieldable connection insures a full closing of the flap valve despite Variations that may exist or develop and that would otherwise require precision work or that would result in leakage. The spring is fixed to provide a slight expansion of the spring when the flap valve is closed and the flap valve will be moved to the dotted line open position when valve 10 is closed.

The numeral 26 designates a flexible wire that extends from the valve handle 11 through tubular metal sheath 29 to an operating handle 27 suitably mounted in a vertical position on the cross strip 12. The tubular sheath 29, through which the wire 26 passes in the operation of the handle 27, is fixedly connected to the conduit 7' by spaced clamps 28. Thus, the covering and the conduit are retained within the bowl in a bowed configuration.

It is pertinent to note that substantially the entire device, with the exception of the conduit 7 and the horizontal portion 7, strip 12, nozzle 16, and the handle 27 of the Bowden cable, are within the bowl of the toilet, and are readily removable therefrom, being merely held in place by a person seated on the toilet seat.

Obviously the device, being mounted to rock slightly about the longitudinal axis of strip 12 is adapted to be automatically vertically adjustable, under the weight of a person, and the fact that the strip is movable to any desired position on the seat 13 also enables any desired horizontal adjustment.

The simultaneous actuation of valves 10, 19 is desirable and enables control of the flushing throughout the range of the valves.

It is to be understood that the form of my invention herewith shown and described is to be taken as the preferred example of the same and that various changes relative to the size, shape, material and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
